The quality and standard of South African examination questions for the grade 12 examination have become an important issue for the South African education system. So far, the focus of empirical research has been on factors that lead to poor performance in the Physical sciences as well as the alignment of the grade 12 Physical Sciences examination with the core curriculum in South Africa. On the contrary, this research paper focuses on a different aspect: the weaknesses and the strengths of the Physics examination questions. It addresses the question of how the Physics examination questions cover higher and lower order level questions in the Bloom’s revised taxonomy. To answer this question, the Physics examination questions of the year 2014 and 2015 were analysed using Bloom’s revised taxonomy of learning objectives. The examination questions were codified and the frequencies and percentages of occurrence of different learning objectives were calculated. The results show that third level cognitive skills were more prevalent than other ones. Furthermore, examiners asked questions that require application and few questions requiring the recall of knowledge. Keywords: physics examination, revised Bloom’s taxonomy, quality of education.

Pedagogical Approaches

This study investigated appropriate pedagogical techniques for workplace e-learning programs in the South African wood products (furniture) manufacturing sector. The study found that learners responded favourably to constructivist teaching approaches, such as asynchronous discussions, open-ended task-based activities, and assignments incorporating authentic, real-world examples. Learners viewed constructivist activities to be more useful than quizzes and traditional essay-based assignments, as they allowed new concepts to be learned in context and were perceived to promote deeper understanding of the subject matter. Nevertheless, they valued the inclusion of a blend of pedagogical approaches in the course design, as this enabled them to approach and analyze new concepts in an assortment of ways. Learners placed importance on regular interaction with other learners and course instructors, and were strongly in favour of including face-to-face components in Web-based courses.

Round Wood

Construction wood has to meet high requirements for loads capacity. Thanks to the selection and adequate classification of raw materials it is possible to decide how specific wood products can and should be used. The usage of solid wood for structural elements purposes has been precisely classified and specified in standardized requirements. Twelve classes of structural timber, ranging from C14 to C50, have been identified for softwood. Only part of Polish raw wood meets the standards of strength classes required in the building industry, as its strength corresponds to classes C24 and C30. A conclusion from research on the assortment structure of the raw materials in Poland was formed that it is particularly important to sort wood effectively according to its quality and intended use during processing. The material and strength efficiency is the main indicator of rational use of wood. The research resulted in setting the initial classification limits of selected round wood groups according to its strength. Properties determining the possibilities of obtaining a high quality product from the available raw wood material were taken into account in the research. Crucial factor was to select the proper research technology of determining dependencies between the applied research methodology and the defined wood quality, sorting class and strength class. The lower limit of availability of raw material with appropriate technical characteristics is determined during the selection of the research formula.

Service Offering

This research verifies the usefulness of the service quality principles and the Basic Service Package elements of the Augmented Service Offering model in measuring perceived service quality of a complex wildlife tourist activity. In addition, it determines the existence of a quality-satisfaction and quality-intention link. The South African hunting safari serves as an illustrating example. As U.S. hunters constitute the largest cluster of non-domestic customers in the South African safari hunting industry, their perceptions of service quality and the resulting satisfaction and behavioral intentions can significantly impact the sustainable competitiveness and profitability of safari service providers. The results negate the applicability of the SERVQUAL model, but confirm the usefulness of the Augmented Service Offering model in measuring the service quality of the safari hunt and in identifying areas of service failure and adequate service performance. The regression analysis confirmed the existence of important quality-satisfaction and quality-intention links.

Vacuum Method

Wood drying is an important process for adding value and manufacturing innovative products. Eucalyptus nitens wood is inherently difficult to dry because of its natural propensity for checking as well as collapse and shrinkage. Lumber recovery after industrial drying of eucalypts is also very low. This study measured the wood quality of E. nitens juvenile wood (13 mm thickness) after radio-frequency vacuum (RFV) drying and wood dried in a conventional kiln dryer (KD). Drying cycles were performed using a radio frequency vacuum dryer with a 3 m3 of capacity and convective kiln-dryer equipment with a 3.5 m3 of capacity. The results showed that the drying time using the radio frequency vacuum method was reduced by 47% when compared to conventional kiln drying. The shrinkage was significantly lower in the RFV than in the conventional KD. The volumetric collapse decreased by approximately 60% in the RFV drying. RFV drying of E. nitens juvenile wood improves the wood quality for solid wood products because the intensity of surface checking and collapse are reduced.
